Do sunscreens really block the sun?

Curious about natural dermatology for aging and cancer prevention? One of the reasonsthat I’m such an advocate of hats and clothing is that sun screens don’t really block the sun. They do take the sun’s energy and change it into a more harmless form of energy so that there is not a sun burn, but still some of that energy gets through. That energy can cause damage especially if you apply sunscreen on and then spend a lot of time out in the sun.

With just sunscreen, you get some of that energy coming through all day long that can be causing aging, and even potentially future skin cancer. It’s important to remember that even the metallic sunscreens like zinc and titanium are usually zinc and titanium salts, they’re not the metal. You do get some energy coming through, even using those. It’s very important to remember that you need other kinds of ways of blocking the sun. The sun screen is just an added benefit to protect against reflected rays.
